【问题描述】：

我会做这些事情已经有一段时间了

 ➜  ~  cd ~/project

    ➜  project  source vProject/bin/activate

    (vProject)➜  project  cd edu

    (vProject)➜  edu  pip install pillow

    Requirement already satisfied (use --upgrade to upgrade): pillow in /home/hadi/project/vProject/lib/python2.7/site-packages

以及我安装 psycopg2 的那一刻

(vProject)➜ edu pip install psycopg2

我收到了这个错误

我之前安装过gcc

标签： python c++ linux python-2.7 fedora

【解决方案1】：

您缺少安装它所需的库。我相信你需要安装的包是postgresql-devel。

【讨论】：

【解决方案2】：

根据您在 virtualenv 中运行的 Python 版本，运行以下命令之一：

Python 2.x：

sudo dnf install python-devel

Python 3.x：

sudo dnf install python3-devel

【讨论】：

【解决方案3】：

第 1 步：对于 rpm linux

sudo dnf install python-devel postgresql-devel rpm-build

deb linux

sudo apt-get install libpq-dev python-dev build-essential

第 2 步：在你里面virtualenv

pip install psycopg2

【讨论】：

同样的问题，但来自gcc 命令的错误是另一个丢失的文件：./psycopg/psycopg.h:31:22: fatal error: libpq-fe.h: No such file or directory。我已经看到对apt-get install libpq-dev 的建议，但无济于事。此外，在venv 之外安装psycopg2 也可以正常工作。有关如何解决此丢失文件的任何建议？

【解决方案4】：

试试这个，它适用于我我正在使用 fedora 33

pip install psycopg2-binary

【讨论】：

【解决方案5】：

运行这个命令对我有用

sudo dnf install python3-devel
